Key labels can be shown if you turn on “Show Shift Hints” in PadKeys Settings. (There’s a video on our YouTube channel about accessing Settings if you’re having trouble getting it open.) Long-press menus are there for many keys. Hitting opt will show you which ones with a dot in the upper left.

We have no plans for layout changes or emoji — we recommending installing a specialist keyboard (iOS built-in or third-party) for that and switch back and forth w/Globe key.
